About this reader
This reading passage, 'The Mass of a Proton,' introduces middle school students to one of the smallest yet most important particles in an atom—the proton. With a mass of 1.67 × 10⁻²⁷ kilograms, the proton plays a key role in determining the atomic mass and identity of an element. The passage explains that protons are located in the nucleus of atoms, carry a positive charge, and—along with neutrons—account for nearly all of an atom’s mass. Aligned with NGSS standard MS-PS1-1, which focuses on the structure and properties of matter, the passage also supports Common Core standards like RI.6.1 and RI.6.4. The language is clear and accessible, making it ideal for middle grade readers. Includes 8 multiple choice questions, vocabulary practice, and a fun fact to boost engagement. Perfect for cross-curricular instruction that builds science and literacy skills.
